It is not expensive, good recording quality, works properly, like clockwork, touch control. The viewing angle of the main camera is 140 degrees, the secondary one is 90, this is more than enough to capture the roadway, I didn’t need very large angles, this is superfluous and the quality can be distorted. The screen is large, bright, good picture. The second camera, I have it for parking and for monitoring what is happening behind my car, but in general, it can be placed anywhere in the cabin, from a convenient angle. I am satisfied.
